  • the control member 11 which consists of a plate of ferromagnetic material, has two opposite lugs 12 adapted to engage in the opposite lateral slots 9 and a tag 13 adapted to engage in the upper aperture 1li.
  • the opposite lugs 12 when engaged in the lateral slots 9 effectively form two journals and associated bearings.
  • the holding device comprises two permanent magnets 14 which are secured on the chassis 3 and the pole faces of which slightly protrude from the front side c.
  • the plate 11 is provided with apertures 15 arranged opposite certain ones of the push-buttons 6.
  • the operator inserts the journals 12 in the bearings 9 and then pivot the plate so as to introduce it in the guiding frame.
  • the ferromagnetic plate 11 is maintained in position by the magnetic attraction of the permanent magnets and in order to remove the plate the operator exerts a thrust f (FlG. l) on the tag 13 and then removes the plate.
  • the control device may comprise any number of switches up to 20 and more. Further the switches may be simple as shown or multiple.
  • the pushbuttons 6 may alternatively operate changeover switches or commutators.
  • control device permits of a considerable number of different commutations while retaining complete reliability.
  • the various plates of a set of control members preferably are marked in any suitable manner, for example, by different colours, each colour corresponding to a particular operation of the apparatus or machine provided with the described control device.
  • control device may be provided with push-button switches of any known type, for example, commercially available switches, commutators and change-over switches.
  • each switch member i1 etc. is provided with a slidable pin 6 which is normally not closed.
  • the pins may be brought into engagement with a control member 11 hinged by pin 17, after which the plate 11 is held in its operative position (shown) and maintained in this position by a bolt 19 pivoted upon a pin 18.
  • one of the edges of the plate 11 may be inserted in a rail 2t) secured on chassis 3.
  • the plate may be inserted under the rail portion 21 at an angle to the chassis and then swung into the operative position.
  • the retaining face 21 and bolts 19 maintain the plate 11 in the operative position.
  • the ferromagnetic plate 11 is provided with guide orifices 22 (only two of which are shown).
  • the orifices 22 are intended to co-operate with guiding pins 23 secured to 3 the front side of the chassis.
  • the plate l1 is then drawn into the 4operative position shown by two permanent magnets 2d.
  • the apertures 15 may be replaced by depressions or grooves.
  • the plate l1 one of its larger sides may be provided with slots, grooves or projections disposed opposite the push-buttons to be operated or not operated.
  • the switches il to i6 or some of them may be opening switches, that is to say that loperation of the respective push-buttons by the plate 11 results in electric contacts being opened.
  • the second embodiment of the control device shown in FIGURES 7 to 9 is especially intended for controlling washing machines.
  • This control device comprises, sirnilarly to the rst embodiment, switches secured to a chassis 3 and adapted to be operated by means of pushbuttons ti from the front side of the chassis.

  • pointer and its drive may alternatively be designed differently in any known manner.
  • the circuits may be connected so that when the operator during a cycle moves the plate from its operative position to its open position the operation being performed is stopped and the switchboard skips all the following operations with the exception of the final draining so that the machine is again in the rest position and ready to commence any cycle.
